Power, Temperature, & Noise
As always, last but not least is our look at power, temperature, and noise. Next to price and performance of course, these are some of the most important aspects of a GPU, due in large part to the impact of noise. All things considered, a loud card is undesirable unless there’s a sufficiently good reason – or sufficiently good performance – to ignore the noise.
Unfortunately we don’t have any tools that can read the GPU voltage on the ASUS card, so we’ll jump right into average clockspeeds.

The ASUS R9 380X has no problem holding its full boost clockspeed in games, both at its stock speed of 1030MHz and when downclocked to 970MHz.
Starting with idle power consumption, the ASUS card comes in right where we’d expect it. 75-76W is typical for a Tonga card on our GPU testbed.
Moving on to power consumption under Crysis 3, like so many other aspects of R9 380X, its performance here is very close to the original R9 380. Power consumption is up slightly thanks to the additional CUs and the additional CPU load from the higher framerate, with the reference clocked R9 380X coming in at 299W, while ASUS’s factory overclock pushes that to 304W.
The problem for AMD is that this is smack-dab in GTX 970 territory. Meanwhile the GTX 960, though slightly slower, is drawing 74W less at the wall. R9 380 just wasn’t very competitive on power consumption compared to Maxwell, and R9 380X doesn’t do anything to change this. AMD’s power draw under games is essentially one class worse than NVIDIA’s – the R9 380X draws power like a GTX 970, but delivers performance only slightly ahead of a GTX 960.
The one bit of good news here for AMD is that while the power consumption of the R9 380X isn’t great, it’s still better balanced than the R9 390. With AMD opting to push the envelope there to maintain price/performance parity with the GTX 970, while the R9 380X is a fair bit slower than the R9 390, it saves a lot of power in the process. And for that matter the R9 380X shows a slight edge over the 7970, delivering similar gaming performance for around 16W less at the wall.
Moving over to FurMark our results get compressed by quite a bit (we’re using a GTX 960 with a fairly high power limit), but even then the R9 380X’s power consumption isn’t in AMD’s favor. At best we can say it’s between the GTX 960 and GTX 970, with the former offering performance not too far off for less power.
Otherwise as was the case with Crysis 3, the R9 380X holds a slight edge over the 7970 on power consumption. This despite the fact that the R9 380X uses AMD’s newer throttling technology, and consequently it gets closer to its true board limit than the 7970 ever did.
With idle temperatures ASUS’s 0db Fan technology doesn’t hamper the R9 380X at all. Even without any direct fan airflow the STRIX R9 380X holds at 30C.
Load temperatures also look good. ASUS’s sweet spot seems to be around 70C – right where we like to see it for an open air cooled card – with the R9 380X reaching equilibrium at 67C for Crysis 3 and 71C for FurMark.
Finally with idle noise, the zero fan speed idle technology on the STRIX lineup means that the STRIX R9 380X gets top marks here. At 36.4dB the only noise coming from our system is closed loop liquid cooler for the CPU. The video card is completely silent.
Shifting over to load noise levels then, the STRIX R9 380X continues to impress. With Crysis 3 the card tops out at 38.9dB – less then 3dB off of our noise floor – and that goes for both when the card is operating at AMD’s reference clocks and ASUS’s factory overclock. At this point the STRIX R9 380X is next-to-silent; it would be hard to do too much better without using an entirely passive cooling setup. So for ASUS to dissipate what we estimate to be 175W or so of heat while making this little noise is nothing short of impressive.
Meanwhile with FurMark the ASUS card needs to work a bit harder, but it still offers very good results. Even with the card maxed out we’re looking at just 41.4dB. The STRIX R9 380X isn’t silent, but it gets surprisingly close for such a powerful card.

I had the Asus GTX970 Turbo and it had the grindiest ball bearing fan I've ever heard. It brought me back to the Athlon's YS Tech and Delta days. The "Titan" cooler on my old GTX770 was virtually silent in comparison.So Asus has their duds, but the Strix seems to be a great cooler if you don't need a blower...but many of us do. In a bit a shame toward Asus, I replaced their Turbo with a PNY 970 (also a blower) and the PNY feels cheaper, but cools better and makes less noise.

Don't get me wrong here, I really like ASUS stuff - but they have let me down several times on cheapo video card cooling systems. Nasty sleeve bearing fans on half-height Radeon 6580s that vibrate then seize, which was really cheeky considering the box had a "high quality fan omg!!" thing as part of its marketing material.Ended up replacing the half-height card with a passively cooled one - and a nearby 80 mm case fan - so I couldn't have a crappy onboard fan, since every other card on the market seemed to be carrying the same stupid POS fan. I couldn't even spend more to get a better one!

I wouldn't get anything other than a EVGA cooling system.. I have the ACX 2.0 verions of a 970 and a 980 ti, and they are really fantastic... lolSamus - Tuesday, November 24, 2015 - link
EVGA is great, but they don't make Radeon cards. It's important to point out, as well, that EVGA is actually NOT NVidia's OEM partner. PNY is. PNY makes a ton of cards based off NVidia's reference designs, which I think are the best. The Titan cooler used on reference 770/780/970/980 GPU's, specifically the vapor-chamber variant, is unsurpassed by any other partners'. That's why almost every partner makes at least one variant of these GPU's with the Titan cooler. They don't make many, because the rumor is NVidia charges $30 for the vapor chamber cooler and it is more expensive to manufacture the cards because of the installation (GPU binding) technique.But EVGA has probably the best, easiest to deal with warranty. Unfortunately I've had to use it.

If use Sapphire's DualX and triX for the AMD camp imho.I'm still with my trusty 7950 dual X OC. and works wonders!

From what I understand Sapphire started with the vapor chamber type cards on a few of their Radeons 6 years ago.. Interesting that Nvidia went that route. I'd never heard of any other company doing it before and didn't know they had that on their high end coolers..maecenas - Monday, November 23, 2015 - link
Fair enough, I am generalizing based on an observation pool of 2, which I shouldn't do, but I really enjoy having a silent GPU that doesn't go over 65C! It seems that cooling technology has progressed across the board, which is great news for everyone.BurntMyBacon - Tuesday, November 24, 2015 - link
@maecenasI agree they have a nice cooling system. They may even have the best at the moment. That said, I do believe they have some good competition in this area. MSI impressed me with their Twin Frozer design back before Asus had a DirectCU design out. They've been constantly improving since then. Saphire (much as I dislike them) released some very appealing vapor chamber designs. EVGA had pretty decent blower coolers, but nothing really standout until their second revision of their non-blower design (ACX 2.0). The ACX 2.0+ is copper heaven. I don't really favor designs that just throw another fan at it without really giving much thought to the heatsink design like Gigabyte's Windforce cards. I feel like MSI set the bar with their original Twin Frozer cards and since then, MSI, Asus, Saphire (sigh), and now EVGA have been vying for dominance in the cooling department.

Strix is nice but MSI's cooling solution is just as good.olivaw - Monday, November 23, 2015 - link
Did I miss the GTX 960 review???
